Third CIRCULAIR Webinar on 16 December 2025
Third CIRCULAIR webinar on 16 December 2025
The third CIRCULAIR webinar will be organized on Tuesday 16 December 2025 from 16.00 to 17.00 (CET) and will explore recent breakthroughs in bioliquid upgrading, with a special focus on hydroprocessing.
Abstract:
Thermochemical processing of biomass offers a powerful route to transform low-grade or waste materials into valuable biofuels, including sustainable aviation fuel (SAF). However, products from processes such as hydrothermal liquefaction (HTL) and pyrolysis require upgrading to meet fuel standards. In this webinar, we will explore recent breakthroughs in bioliquid upgrading, with a special focus on hydroprocessing. Daniele Castello (Aalborg University, Denmark) will share the latest results from the CIRCULAIR project on upgrading HTL biocrudes derived from agricultural residues. Jens Anders Hansen (Topsoe, Denmark) will present cutting-edge work on converting sewage sludge pyrolysis oil into SAF.
Agenda:
- “Upgrading HTL biocrudes from agricultural waste: from pretreatment to innovative processing solutions” by Daniele Castello (Aalborg University)
- “Upgrading of sewage sludge derived pyrolysis oil to sustainable aviation fuel” by Jens Anders Hansen (TOPSOE)
Registration is now open.
